RAZOR-STROP.-

SPECIFICATION forming part of Letters Patent No. 556,363, dated March17, 1896.

Application filed April 27, 1895.

To all whom it may concern:

Be it known that I, PATRICK C. MCGRATH, a citizen of the United States,residing at Rutland, in the county of Rutland and State of Vermont, haveinvented a certain newand useful Improvement in Razor-Strops, of whichthe following is a full, clear, and exact description.

The object of this invention is to provide an inexpensive and efficientstrop for insuring the retention of the concaved ground edge of therazor and for toning the edge down fine and for finishing up to a finecuttingedge, all as I will proceed now more particularly to set forthand finally claim.

In the accompanying drawings, illustrating my invention, in the twofigures of which like parts are similarly designated, Figure 1 is anelevation looking at one of the four sides, and Fig. 2 is an elevationlooking at a side at right angles to that exposed in Fig. 1.

In the preferred form of my invention I employ a solid foundation-blocka, of wood or other material, having a handle 19. One side 0 of thisblock is made convex, the radius upon which the arc is described beingabout six inches in length, and the opposite side, (Z, is also madeconvex on the arc of a circle having a much greater radius. The twoadjacent sides e and fare fiat, and the body or block a may be piercedtransversely, as at g and h, to form pockets for the reception of theusual dressing materials for the strop, these pockets being closed by aswingplate a secured to the block, as by a screw j. Instead of aswinging cover for these pockets, I may use a sliding cover or any othersuitable stoppering or closing device.

The sides 0, (Z, and e may be covered with leather, as indicated, orwith other usual material employed in strops or hones or similar cutleryor razor-sharpening devices.

My invention may be applied to hones of stone.

The edge or side 0 is designed by its curvature for use in keeping theedge of the razor serial No. 547,349. (No model.)

concaved down as originally ground; and it is obvious that by using thisside it will be impossible to convex or round the edge of the razor, asso frequently happens in the use of the common flat strops. The side discurved in the manner shown in order to effect the toning down of theedge of the razor, and the flat side e is used to finish the edge andgive the razor a superior cutting quality. All of the sides are flattransversely or in the direc tion of the width of the strop in order toinsure even work upon the razors edge. These several functions of theseveral sides, of course, will depend largely upon the quality orcharacter of the covering applied to these sides, and it is within myinvention to use a character or quality of covering adapted to insurethe ends hereinbefore stated.

\Vhat I claim is 1. As an improved article of manufacture, thewithin-described razor-strop composed of a solid foundation-block,having three of its sides constructed as sharpening mediums, one side,0, being of a convexity co-ordinate with the concavity of the edge ofthe razor, and another side, (I, also being convex, the arc of itsconvexity being described by a radius of a greater length than that ofthe arc of convexity of the first-named side, and the third side, 6,being fiat, all of said sides being flat in the direction of the widthof the strop, substantially as shown.

2. A razor-strop composed of a solid foundation-block, having three ofits sides, 0, cl, 6, constructed as sharpening mediums, two sides beingconvex and their convexity differing in curvature, and the third sidebeing fiat, all of said sides being flat transversely, the remainingside being provided with covered pockets,substantially as shown anddescribed.

In testimony whereof I have hereunto set my hand this 24th day of April,A. D. 1895.
